Oftentimes, Pink Floyd's propensity for social commentary, progress and experimentation can get quite... ''unnerving''...

Sometimes, Pink Floyd's nature for social commentary, progress and experiment can get a bit... ''unnerving''...

* "Dogs", the 17-minute epic that comprises virtually the entire first half of ''Animals'', is a thoroughly chilling composition in every conceivable sense of the word. From the twistedly psychedelic keyboard effects to the raw, brittle acoustic guitar, the prevailing mood of the entire track is utterly dour. The lyrics are a stark and unflinchingly accurate portrayal of the aggressive, egomaniacal businessmen who exploit the people around them to get ahead. One line in particular stands out, describing the eventual fate of those types:

* "Sheep" may also qualify as this. Halfway into the song, there is very eerie Hammond organ, followed by a corrupted version of Psalm 23 which could give you nightmares:

--> "''...I like to picture "Welcome to the Machine" as a long, creepy, but breathtaking [[{{Hellevator}} elevator journey]] to the top of [[NightmarishFactory The Factory]], with [[AndIMustScream the souls of miriads (sic) of unfortunate victims trapped]] on [[ImpossiblyTallTower the countless stories]]; and then, at the very top of it all, you are greeted by the Uberboss, a [[TheDevilIsALoser somewhat ignorant]] ("by the way, which one's Pink?"), but [[DevilInPlainSight totally efficient]] [[{{Satan}} Lucifer]] model in its own right. (Maybe they should have brought in Music/AliceCooper to sing the song instead. Or Music/{{Meatloaf}}.)''"

''TheDarkSideOfTheMoon'' and ''[[Music/TheWall The Wall]]'' have their [[NightmareFuel/TheDarkSideOfTheMoon own]] [[NightmareFuel/TheWall pages]].

'''Music/TheWall'''
* Most of the animation from the 1982 film adaptation of ''Music/TheWall''.
** Speaking of ''Music/TheWall'', while the entire album is creepy, two tracks stand out. Most of "Don't Leave Me Now" sounds extremely disturbing; think of a funeral dirge with a guy lamenting the collapse of his abusive marriage and you'll get the idea. And then you have "Is There Anybody Out There?", which is reminiscent of something from a horror movie. Thank God it turns into a nice-sounding guitar melody.
** "Goodbye Blue Sky", particularly the images seen in the music video. It starts with a soothing guitar riff, then the terror sets in. "D-D-D-DID YOU SEE THE FRIGHTENED ONES? D-D-D-DID YOU HEAR THE FALLING BOMBS?"
*** [[HarbingerOfImpendingDoom "Look mummy, there's an aeroplane up in the sky."]]
*** A dove suddenly becoming a dark metallic eagle.
*** The metallic eagle grabbing a bit of ground that actually bleeds.
*** A warlord with glowing headlights for eyes that morphs into a factory of steel.
*** An army of bombers emerging from the towering structure.
*** The Union Jack (British flag) on a post becoming a blood-red cross.
*** The soldiers with skulls for heads.
*** Strange creatures wearing gas masks running for cover.
*** Anything else becoming a cross.
*** Blood trickling through a storm drain.
** From "The Happiest Days of Our Lives": ''"But in the town it was well known when they got home at night, their fat, psychopathic wives would '''thrash them''' within inches of their lives!''
** The meat grinder in "Another Brick in the Wall (Part 2)". They were getting ground up like Play-Doh.
** The animated piece for "Empty Spaces" and "What Shall We Do Now?"
*** The two animated flowers. The female quickly snatches the male in her jaws and becomes a horrid creature.
*** The wall being constructed.
*** A sea of beings with the same featureless faces as those in the school.
*** [[AndIMustScream The screaming face emerging from the wall.]]
*** Everything the wall passes becoming corrupted.
** The creepy-ass mantis / butterfly / flower / vagina monster ''thing'' that the shadow of Pink's wife turns into near the end of the "Don't Leave Me Now" sequence.
** The animation that accompanies "The Trial" in the movie also qualifies. Pretty much everything in that sequence counts here.
*** Pink's wife definitely qualifies. She first appears as a scorpion like creature who manifests from the wall, impales Pink (now a ragdoll) with her tail, and then morphs into a siren with elongated limbs and flaming eyes.
*** Pink's mother is even more frightening. She first flies out of the wall as an airplane, then morphs into a talking labia, grabbing Pink with an umbilical cord.
*** The School-master is pretty creepy too, with his sickly grey skin, constantly moving tufts of hair, Magnifying glass-like eyes, hammer shaped head and creepy marionette motif.
*** The judge from "The Trial" is probably the most nightmarish of all. He starts off as a giant worm, and as his verse begins, he transforms into a giant talking pair of buttocks, complete with a judge's wig on top and a pair of backwards facing legs. What makes it all the more frightening is how the animation manages to make it look vaguely like a human face, as the rectum is the mouth and the scrotum is meant to look like a chin. [[SarcasmMode It's not as tame as it sounds.]]
** "Run Like Hell". ''"With your empty smile and your hungry heart / Feel the bile rising from your guilty past / With your nerves in tatters / When the cockleshell shatters / And the hammers batter down the door / You better run!"''
*** Similarly, "Waiting for the Worms":
---->"'''Waiting''' to put on a black shirt!\\
'''Waiting''' to weed out the weaklings!\\
'''Waiting''' to smash in their windows\\
And kick in their doors!\\
'''Waiting''' for the Final Solution\\
To strengthen the strain!\\
'''Waiting''' to follow [[ANaziByAnyOtherName the Worms]]!\\
'''Waiting''' to turn on the showers\\
And fire the ovens!\\
'''Waiting''' for the queens and the coons\\
and the reds and the Jews!"
*** And "In the Flesh", the song that directly precedes these two:
---->"Are there any queers in the theatre tonight?\\
Get 'em up against the wall. (''''gainst! The! Wall!''')\\
There's one in the spotlight,\\
He don't look right to me!\\
Get him up against the wall. (''''gainst! The! Wall!''')\\
And that one looks Jewish!\\
And that one's a '''''coon'''''!\\
Who let all this riff-raff into the room?\\
There's one smoking a joint!\\
And another with spots!\\
If I had my way,\\
I'd have all of ya shot!"
*** Roger Waters may be mocking racism, homophobia, antisemitism, ect.; but it could easily be taken out of context.
** "Hey You" starts with a frail, haunting guitar riff accompanied by a few notes played on a fretless bass and a Fender Rhodes electric piano. The song gets more and more desperate in tone throughout, right up to its climactic end with Roger Waters wailing at the top of his lungs. Also notable is the line directly preceding a reprise of the song's intro: "No matter how he tried, he could not break free -- and the worms ate into his brain." This is easily one of Pink Floyd's darkest songs.
** "One of My Turns" describes the decline of Pink's marriage in rather excruciating detail. ''"Day after day, love turns grey, like the skin on a dying man." "I feel cold as a razor blade, tight as a tourniquet, dry as a funeral drum!"'' Then he goes through one of his "turns" -- a psychotic break where he goes berserk.
** "Goodbye Cruel World". Despite not ''actually'' having anything to do with suicide, the lyrics certainly make it seem that way, especially if they're taken out of context from the rest of the album. Fun fact: The [[GoodbyeCruelWorld trope of the same name]] uses an excerpt from this song as part of its introduction.

Sometimes Pink Floyd's nature for social commentary, progress and experiment can get a bit... Unnerving...

* The last minute of "Absolute Curtains", which is a creepy distorted tribal chant.

'''Music/TheDarkSideOfTheMoon'''
* "On the Run" is a living, breathing scary sound.
* "Time" may sound like an upbeat track at first, but listen closely to the lyrics and you'll realize that it is actually about [[AdultFear how life seems to go by faster as you get older]]. Relative to this theme of time sneaking up on you, the first half a minute also features softly ticking clocks that give way to a loud alarm clock [[JumpScare that can catch first-time listeners off guard.]]
--> ''The sun is the same,\\
in a relative way,\\
but you're older.\\
Shorter of breath\\
and one day closer to death.''
* While the interlocking sounds of "Speak to Me" lie within the bounds of ParanoiaFuel, the segment transforms into pure NightmareFuel right at its end when a sample of Clare Torry's screams from "The Great Gig in the Sky" enters the mix.
* "The Great Gig in the Sky". Their goal was to create a track that simulates the feeling of dying. Let's just say they succeeded. [[TearJerker It's also rather sorrowful,]] [[HarsherInHindsight especially after its composer went there.]]
* "Brain Damage":
--> ''[[SplitPersonalityTakeover There's someone in my head... But it's not me.]]''
--> ''[[SanitySlippageSong You raise the blade, you make the change, you rearrange me 'til I'm sane.]]'' Good grief.
* "I never said I was frightened of dying".
